Well i've booked it for the 29 Oct. Kinda worried. If I wait until I believe I can do it, I may never book it, so taking a chance here.
I understand the OSI model, I know how to configure routers (PPP / HDLC / Frame Relay), I can configure routing protocols (RIP / EIGRP / IGRP / OSPF), I can subnet in a reasonable time, I can configure a switch in the management VLAN, and configure VLANs and dot1q trunking. I understand how access lists work and where to put standard and extended acls.
I need to brush up on my cable distances and ISDN.
Apart from that is there anything I'm missing??
I hate exams but this has to be confronted head-on.

Edit: I've tested myself on the cisco site and come out with scores of +80%. I tested myself last night on the Bright Spark website and go 83% I think with 75 questions.
